APPARATUS FOR COOKING, HEATING, 840.

SPECIFICATION forming part of Letters Patent No. 657,497, datedSeptember 4, 1900.

Application filed March 6, 1900. Serial No. 7,526. (hl'o model.)

To all whom it may concern.-

Be it known that I, EDWARD WILLIAM PAR- ISH, commercial traveler, asubject of the Queen of Great Britain, residing at Parishs Patent SteamJ acketted Cooker Company, Limited, of 97 Queen Victoria street, London,England, have invented certain new and useful ImprovementsinLow-Pressure Steam Apparatus for Cooking, Heating, -Drying,.

Evaporating, Steam-Generating, and Similar Purposes, of which thefollowing is a specification.

This invention relates to apparatus for,

cooking, heating, drying,evaporatin g, steamgenerating, or similarpurposes, and has for its primary object to so construct such apparatusthat a' constant supply of hot water or other liquid can be obtainedtherefrom simultaneously with its employment as a cooker, heater, drier,evaporator, steam-generator, or the like without interfering with itseffectual operation as'such.

According to this invention the water paratus comprises a water-jacketsurround-' ing the cooking part and is connectedwith the water-chamberand the water-space by suitable conduits. The cold water is admitted tothe lower part of the water-jacket from a lateral compartment. The hotwater is withdrawn from the upper part of the water-jacket or of thewater-chamber.

In order that the invention may be clearly understood and readilycarried into effect,it will be described more fully with reference tothe accompanying drawings,in which- Figure 1 is a vertical section, andFig. 2 a transverse section, on the. line'l 1, showing a satisfactoryform of the apparatus.

The part of the apparatus wherein the cooking, heating, or otheraforesaid operation is effected comprises a pan A, within which thesubstance to be cooked or similarly treated is placed, such pan beingsurrounded by a space or chamber A containing water or other suitableliquid, which is heated from a furnace A arranged below the said spaceor chamber. The bottom of the pan A is preferably made with a concavitya in order to assist in preventing the incoming cold water from tooquickly rising as it gets heated in the space or chamber A and from toosuddenly reducing the temperature of the water at the upper portion ofthis space or chamber. Baffle-plates or any other suitable contrivancemay, however, be employed for this purpose. The water-space A isconnected at the bottom by conduits b to the upper part of thewaterchamber B, which is surrounded by the wator-jacket B forming partof the hot-watersupply part of the apparatus. The said water-chamber Bhas a central conical passage B through which the products of combustionor heated gases from the furnace A pass. The lower part of thewater-jacket is connected by conduits b to the lower part of the saidwater-chamber, and the upper part of said water-jacket communicates at bwith the upper part of the water-space A into which the cooking-pan Adips.

B is a lateral chamber or compartment intowhich the cold water entersand from which it flows through the opening b to the waterjacket B 1) isthe pipe through which the hot water is withdrawn from the apparatus.

The incoming cold water enters the mouth of the lateral compartment orchamber 13 and reaches the Water-chamber B through the conduits bwherein it rises and reaches the water-space A through the conduits b, acorresponding quantity of hot Water escaping through a suitablereceptacle. The cold water as it becomes heated rises to the surface ofthe said water-space A ready to pass away through the pipe b, whenanother quantity of cold water is admitted to the lateral compartment orchamber B It will be understood that so long as no cold water is pouredor admitted into the chamber 13 no hot water will escape from theapparatus, and that by regulating the quantity of cold water enteringsaid chambera constant supply of hot water will be obtained from theapparatus through the said pipe b.

Having thus described my invention, wha I claim is 1. Inapparatus forcooking, heating and similar purposes and for simultaneously supplyinghot liquid, the combination with the cooking or heating chamber, of anannular chamber surrounding the liquid-space of said latter chamber an dcommunicating therewith at its upper part, of anoutlet-pipe forhot waterfrom the upper -part of said liquidspace, of an intermediateliquid-chamber lo-- cated beneath the said liquid-space andcommunicatingtherewith,of lateral conduits con= necting the said annularchamber and the said intermediate chamber near their lower ends, and ofan external compartment which 1 is open at the top and communicates withthe said annular chamber through an open-' ing near the bottom thereof,substantially as 1' and for thepurpose described.

2. In apparatus for cooking, heating and similar purposes and forsimultaneously sup plying hot liquid, the combination With'the 5 cookingor heating chamber, of an annular chamber surroundingthe liquid-space ofsaid latter chamber and communicating therewith at its upper part, of anoutlet-pipe for: hot water from the upper part of said liquid-space, ,ofanintermediate liquid-chamber having a central flue therein and locatedbeneath the said liquid-space and communicating therewith, of lateralconduits connecting the said ,annular chamberand the said intermediatechamber near their lower ends, of an external compartment which is openat the top and communicates with thesaid annular chamber through anopening near the bottom thereof andof a furnace located beneath saidcentral flue in the intermediate liquid-chamber, .all substantially asand for the purpose der scribed. 1 1

In testimony whereof I have hereunto set my hand, in presence of twosubscribing witfnesses, this 23d day of February, 1900.

EDWARD WILLIAM PARISH.
